Classroom Reef Aquarium at Sequoia Middle School

Posted by Staff on 3/27/2015 to

We are working on the plumbing now and hope to have water in it within two weeks. We
have set up the AquaFX Barracuda on a counter until I decide its permanent
location and the aquarium's auto top off plans. Turns out the classroom sinks
have higher TDS than those in the storeroom where I had planned to run the
unit. No problem! TDS around 350 taken down to 0 with 1.5x waste water which we use on rugged outdoor plants. I will learn more about adjustments and all
things RODI, but the unit is great and I really appreciate your donation of
this integral part of our aquarium!

I will send an update once the tank is up and running. For now,
students have learned a bit about the different stages of filtration. Groups of
students helped with initial setup, measured and made logs of input and output
TDS, measured the flow rate of exiting water for the tank (blue line) and
plants (yellow line) and figured ratios of pure water to waste water as we
adjusted the waste water line with a flow restrictor. The Barracuda has already
provided these great real-world learning opportunities!
